Valid Devices

For valid device address ranges, see "Device Addresses" on page 3-1.

Internal relays M0 through M1277 can be assigned as D1. Special internal relays cannot be assigned as D1.

When T (timer) or C (counter) is used as S1 or S2, the timer/counter current value (TC or CC) is displayed. When T (timer) or C (counter) is used as D1, the data is written in as a preset value (TP or CP) which can be 0 through 65535.

Since the Boolean computation instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Valid Data Types

Example: XORW

To convert optional output status among a series of 10 output points, use the XORW instruction in combination with 10 internal relay points.

W (word) X When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the source or destination, 16 points (word data) or 32 points (double-word data) are used. When repeat is assigned for a bit device, the quantity of device bits increases in 16- or 32-point increments.

When a word device such as T (timer), C (counter), or D (data register) is assigned as the source or destination, 1 point (word data) or 2 points (double-word data) are used. When repeat is assigned for a word device, the quantity of device words increases in 1- or 2-point increments.

When input I1 is turned on, the XORW instruction is executed to invert the status of outputs Q0, Q2, Q4, Q6, and Q10.



Repeat Operation in the ANDW, ORW, and XORW Instructions

Source devices S1 and S2 and destination device D1 can be assigned to repeat individually or in combination. When destination device D1 is not designated set to repeat, the final result is set to destination device D1. When repeat is assigned, consecutive devices as many as the repeat cycles starting with the designated device are used. Since the repeat operation works similarly on the ANDW (AND word), ORW (OR word), and XORW (exclusive OR word) instructions, the following examples use the ANDW instruction.

Repeat One Source Device Data Type: Word

When only S1 (source) is assigned to repeat, the final result is set to destination device D1.

Data Type: Double Word

When only S1 (source) is assigned to repeat, the final result is set to destination device D1·D1+1.

Repeat Destination Device Only Data Type: Word

When only D1 (destination) is assigned to repeat, the same result is set to 3 devices starting with D1.


When only D1 (destination) is assigned to repeat, the same result is set to 3 devices starting with D1·D1+1.

Repeat Two Source Devices Data Type: Word

When S1 and S2 (source) are assigned to repeat, the final result is set to destination device D1.


When S1 and S2 (source) are assigned to repeat, the final result is set to destination device D1·D1+1.

10:SHIFT / ROTATE INSTRUCTIONS

IntroductionBit shift instructions are used to shift the data string starting with source device S1 to the left or right by 1 to 15 bits as designated. The data string can be 1 to 65535 bits. The result is set to the source device S1 and special internal relay M8003 (carry or borrow). The LSB or MSB is filled with 0 or 1 as designated.

Bit shift and rotate instructions are used to shift the 16- or 32-bit data string in the designated source device S1 to the left or right by the quantity of bits designated. The result is set to the source device S1 and special internal relay M8003 (carry or borrow).

The BCD left shift instruction shifts the BCD digits in two consecutive data registers to the left.

The word shift instruction is used to move 16-bit data to a destination data register and shifts down the data of subsequent data registers as many as designated.

SFTL (Shift Left)


Valid Devices

For valid device address ranges, see Chapter 5 "Special Functions" - "Device Addresses" in the SmartAXIS Touch User's Manual.

Internal relays M0 through M1277 can be designated as S1. Special internal relays cannot be designated as S1.

Since the SFTL instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

CY S1

When input is on, N_B-bit data string starting with source device S1 is shifted to the left by the quantity of bits assigned by device Bits.

The result is set to source device S1, and the last bit status shifted out is set to special internal relay M8003 (carry or borrow). Zero or 1 assigned by source device S2 is set to the LSB.

BCDLS (BCD Left Shift)


Valid Devices


When T (timer) or C (counter) is used as S2, the timer/counter current value (TC or CC) is displayed.

The number of digits that can be shifted as S2 are 1 through 7.

Make sure that the source data determined by S1 and S1+1 is between 0 and 9999 for each data register. If either source data is over 9999, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. When S2 is higher than 7, a user program execution error will also result.

When a user program execution error occurs, the execution of the instruction is canceled. The data in S1 and S1+1 is left unchanged and the next instruction is executed. For user program execution errors, see "User Program Execution Errors" on page 4-13.

Valid Data Types

When input is on, the 32-bit binary data assigned by S1 is converted into 8 BCD digits, shifted to the left by the quantity of digits assigned by S2, and converted back to 32-bit binary data.

Valid values for each of S1 and S1+1 are 0 through 9999.

The number of digits that can be shifted is 1 through 7.

Zero is set to the lowest digit after each shift.

11:DATA CONVERSION INSTRUCTIONS

IntroductionData conversion instructions convert data to binary, BCD, and ASCII format.

The ENCO (encode), DECO (decode), and BCNT (bit count) instructions processes bit device data.

The ALT (alternate output) instruction turns an output on and off each time an input button is pressed.

The CVDT (convert data) instruction converts data types among W (word), I (integer), D (double word), L (long), and F (float).

The DTDV and DTCB instructions convert data between two one-byte data and one word data. The SWAP exchanges upper and lower byte- or word-data for word- or double-word-data respectively.

HTOB (Hex to BCD)


Valid Devices


Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.

When T (timer) or C (counter) is used as S1, the timer/counter current value (TC or CC) is displayed. When T (timer) or C (counter) is used as D1, the data is written in as a preset value (TP or CP) which can be 0 through 65535.

Valid values for the source device are 0 through 9999 (270Fh) for word data, and 0 through 9999 9999 (5F5 E0FFh) for double-word data. Make sure that the source designated by S1 is within the valid value range. If the source data exceeds the valid range, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

When a user program execution error occurs, the execution of the instruction is canceled. The value of D1 is left unchanged and the next instruction is executed. For user program execution errors, see "User Program Execution Errors" on page 4-13.

Since the HTOB instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Valid Data Types

S1 D1

When input is on, the 16- or 32-bit data assigned by S1 is converted into BCD and stored to the destination assigned by device D1.

Valid values for the source device are 0 through 9999 for word data, and 0 through 9999 9999 for double-word data.

ENCO (Encode)


Valid Devices



Valid values for Bits to designate the quantity of bits searched are 1 through 256. Make sure that the search area designated by S1 plus Bits is within the valid value range. If the source data exceeds the valid range, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.


Since the ENCO instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Examples: ENCO

When input is on, a search begins for the first bit that is set to on. The search begins at S1 until the first set (on) point is located. The number of points from S1 to the first set point (offset) is stored to the destination assigned by device D1.

If no point is on in the searched area, 65535 is stored to D1.

Valid Devices



Valid values for the offset designated by source device S1 are 0 through 255. Make sure that the offset designated by S1 and the last bit of destination data determined by the sum of S1 and D1 are within the valid value range. If the offset or destination data exceeds the valid range, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.


Since the DECO instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

12:WEEK PROGRAMMER INSTRUCTIONS

IntroductionThe Week Programmer instructions turn output on or off at a specified interval.

WEEK (Weekly Timer)

For example, if the ON settings are Monday 13:00 and the OFF settings are Wednesday 18:00, output D1 turns on and off as follows.

Notes:

A maximum of 1 WEEK instruction can be used in a user program.

Normally the output is only updated when the current time and the time for the ON/OFF settings matches, but when the WEEK instruction input changes from off to on, the output state at the current time is determined according to the ON/OFF settings and the output is turned on or off.

When pulse output is enabled, output is turned on for one scan at the ON settings time. For pulse output, see "6. Pulse Output" on page 12-3 or "6. Pulse Output" on page 12-6.

When the ON time is set to a value larger than 2359, the OFF time is set to a value larger than 2400, or the lower 2 digits of ON/OFF time is set to a value larger than 59, a user program execution error will occur.

When the day of the week is not specified, a user program execution error will occur.

The WEEK instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.


Valid Devices

Special data registers cannot be designated as S1. Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.

The WEEK instruction compares the specified day of the week, ON time, and OFF time with the current time and outputs that result.

When the input is on, the output specified by D1 is turned on when the day of the week and the time specified by the ON settings match the current day of the week and time.

The output is also turned off when the day of the week and the time specified by the OFF settings match the current day of the week and time.

The initialization input (M1) turns on with the first scan and the initial settings configured on the P 1 tab are stored in D0 to D2.

The WEEK instruction starts operating according to the values of data registers D0 to D2.

When M10 turns on, the ON time (D1) changes to 9:00 and the OFF time (D2) changes to 17:00.

When M1 turns on, all of the WEEK instruction settings (D0 to D2) return to the initial settings.



YEAR (Yearly Timer)

Notes:

A maximum of 1 YEAR instruction can be used in a user program.

Normally the output is only updated when the current date and the date for the ON/OFF settings matches, but when the YEAR instruction input changes from off to on, the output state at the current date is determined according to the ON/OFF settings and the output is turned on or off.For details, see "Timing Chart when the Input Turns On during the Configured Interval" on page 12-20.

When pulse output is enabled, output is turned on for one scan at the instant (0:00) the date changes to the ON date.When the YEAR instruction input changes from off to on, the output state at the current date is judged according to the ON/OFF settings, and the output is turned on for 1 scan only.For pulse output, see "6. Pulse Output" on page 12-13 or "6. Pulse Output" on page 12-17.

When the year data is outside the range of 2000 to 2099, the month data is outside the range of 1 to 12, the day data is outside the range of 1 to 31, the week data is outside the range of 1 to 5, and the day of the week data is outside the range of 0 to 6, a user program execution error will occur.

The YEAR instruction cannot be used in an interrupt program.If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

When the yearly setting or monthly setting is enabled and a date that does not exist according to the month or year is set for the ON setting or the OFF setting, the output turns on or off on the first day of the next month.


Valid Devices

Special data registers cannot be designated as S1. Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.

The YEAR instruction compares the specified date with the current date and outputs that result. With this instruction you can specify special dates within a one year period.

When the input is on, the output specified by D1 is turned on when the date specified by the ON settings matches the current date.

The output is turned off when the date specified by the OFF settings matches the current date.

When the ON settings are December 15, 2012 and the OFF settings are January 20, 2013, output D1 turns on and off as follows.

Timing Chart when the Input Turns On during the Configured Interval

When the input turns on or off during the interval between the ON settings and the OFF settings, and when the input turns on or off after 0:00 on the date configured by the ON settings when pulse output is enabled, the timing chart is as follows.

When pulse output is disabledWhen the input is turned on, the current date and the ON and OFF settings are compared and the output turns on or off.

[When the input is on before the day specified by the ON settings]

On February 13, 2012, when the input is turned on, the result of the current date compared with the ON and OFF settings is not within the ON and OFF settings (February 15 to February 17, 2012). Therefore, the output remains off.

[When the input is turned on or off during the interval between the ON and OFF settings]

On February 15, 2012, when the input is turned on, the result of the current date compared with the ON and OFF settings is within the ON and OFF settings (February 15 to February 17, 2012). Therefore, the output turns on. The output turns off when the input is turned off.

On February 16, 2012, when the input is turned on, the result of the current date compared with the ON and OFF settings is that the output is turned on.

14:PROGRAM BRANCHING INSTRUCTIONS

IntroductionThe program branching instructions reduce execution time by making it possible to bypass portions of the program whenever certain conditions are not satisfied.

The basic program branching instructions are LABEL and LJMP, which are used to tag an address and jump to the address which has been tagged. Programming tools include “either/or” options between numerous portions of a program and the ability to call one of several subroutines which return execution to where the normal program stopped.

LABEL (Label)


Valid Devices

LJMP (Label Jump)


Valid Devices


Since the LJMP instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Note: Make sure that a LABEL instruction of the label number used for a LJMP instruction is programmed. When designating S1 using other than a constant, the value for the label is a variable. When using a variable for a label, make sure that all probable LABEL numbers are included in the user program. If a matching label does not exist, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

This is the label number, from 0 to 255, used at the program address where the execution of program instructions begins for a program branch.

An END instruction may be used to separate a tagged portion of the program from the main program. In this way, scan time is minimized by not executing the program branch unless input conditions are satisfied.

Note: A single label number cannot be used more than once.

LABEL***


Device Function I Q M R T C D Constant RepeatLabel number Tag for LJMP and LCAL — — — — — — — 0-255 —

When input is on, jump to the address with label 0 through 255 assigned by S1.

When input is off, no jump takes place, and program execution proceeds with the next instruction.

The LJMP instruction is used as an “either/or” choice between two portions of a program. Program execution does not return to the instruction following the LJMP instruction, after the program branch.

14: PROGRAM BRANCHING INSTRUCTIONS


Example: LJMP and LABEL

The following example demonstrates a program that jumps to three different portions of the program depending on the input.

Using the Timer Instruction with Program Branching

When the timer start input of the TML, TIM, TMH or TMS instruction is already on, countdown begins immediately at the location jumped to, starting with the timer current value. When using a program branch, it is important to make sure that timers are initialized when desired, after the jump. If it is necessary to initialize the timer instruction (set to the preset value) after the jump, the timer’s start input should be kept off for one or more scan cycles before initialization. Otherwise, the timer input on will not be recognized.

Using the SOTU/SOTD Instructions with Program Branching

Check that pulse inputs of counters and shift registers, and inputs of single outputs (SOTU and SOTD) are maintained during the jump, if required. Hold the input off for one or more scan cycles after the jump for the rising or falling edge transition to be recognized.

LABEL1

LABEL2

When input I0 is on, program execution jumps to label 0.



M8121 is the 1-sec clock special internal relay.

When jump occurs to label 0, output Q0 oscillates in 1-sec increments.

M8122 is the 100-ms clock special internal relay.

When jump occurs to label 1, output Q1 oscillates in 100-ms increments.



Although normally, the SOTU instruction produces a pulse for one scan, when used in a program branch the SOTU pulse will last only until the next time the same SOTU instruction is executed.

In the example on the left, the program branch will loop as long as internal relay M0 remains on. However, the SOTU produces a pulse output only during the first loop.

Since the END instruction is not executed as long as M0 remains on, output Q1 is not turned on even if input I1 is on.

LCAL (Label Call)


Valid Devices


Since the LCAL instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Note: Make sure that a LABEL instruction of the label number used for a LCAL instruction is programmed. When designating S1 using other than a constant, the value for the label is a variable. When using a variable for a label, make sure that all probable LABEL numbers are included in the user program. If a matching label does not exist, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

LRET (Label Return)


Valid Devices

When input is on, the address with label 0 through 255 assigned by S1 is called. When input is off, no call takes place, and program execution proceeds with the next instruction.

The LCAL instruction calls a subroutine, and returns to the main program after the branch is executed. A LRET instruction (see below) must be placed at the end of a program branch which is called, so that normal program execution resumes by returning to the instruction following the LCAL instruction.

Note: The END instruction must be used to separate the main program from any subroutines called by the LCAL instruction.

A maximum of four LCAL instructions can be nested. When more than four LCAL instructions are nested, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

This instruction is placed at the end of a subroutine called by the LCAL instruction. When the subroutine is completed, normal program execution resumes by returning to the instruction following the LCAL instruction.

The LRET must be placed at the end of the subroutine starting with a LABEL instruction. When the LRET is programmed at other places, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

Correct Structure for Calling Subroutine

When a LCAL instruction is executed, the remaining program instructions on the same rung may not be executed upon return, if input conditions are changed by the subroutine. After the LRET instruction of a subroutine, program execution begins with the instruction following the LCAL instruction, depending on current input condition.

When instructions following a LCAL instruction must be executed after the subroutine is called, make sure the subroutine does not change input conditions unfavorably. In addition, include subsequent instructions in a new ladder line, separated from the LCAL instruction.

Example: LCAL and LRET

The following example demonstrates a program that calls three different portions of program depending on the input. When the subroutine is complete, program execution returns to the instruction following the LCAL instruction.

DJNZ (Decrement Jump Non-zero)


Valid Devices


Since the DJNZ instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

The label number can be 0 through 255. Make sure that a LABEL instruction of the label number used for a DJNZ instruction is programmed. When designating S2 using a data register, the value for the label is a variable. When using a variable for a label, make sure that all probable LABEL numbers are included in the user program. If a matching label does not exist, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

When input is on, the value stored in the data register assigned by S1 is decremented by one and is checked. If the resultant value is not 0, program execution jumps to address with label 0 through 255 assigned by S2. If the decrement results in 0, no jump takes place, and program execution proceeds with the next instruction.

15:REFRESH INSTRUCTIONS

IntroductionThis chapter describes the refresh instructions that update the status of input contacts, external output , and the current value of the high-speed counter, to the latest value during a ladder scan.

IOREF (I/O Refresh)


Valid Devices

Only input or output numbers available on the SmartAXIS can be designated as S1. Input and output numbers for remote I/O slaves cannot be designated as S1. For valid device address ranges, see "Device Addresses" on page 3-1.

Input Device Addresses and Allocated Internal RelaysInternal relays are allocated to each input device as shown in the table below. For example, when I10 is designated as S1, the latest value of I10 is set to M310.

During normal execution of a user program, I/O statuses are refreshed simultaneously when the END instruction is executed at the end of a scan. When a real-time response is needed to execute an interrupt, the IOREF instruction can be used. When the input to the IOREF instruction is turned on, the status of the designated input or output is read or written immediately.

When the IOREF instruction is executed for an input, the filter does not take effect and the input status at the moment is read to a corresponding internal relay.

The actual input status of the same input number is read to the internal input memory when the END instruction is executed as in the normal scanning, then the filter value has effect as designated in the Function Area Settings. See Chapter 5 "Special Functions" - "Input Filter"in the SmartAXIS Pro/Lite User's Manual.

When input is on, 1-bit I/O data assigned by source device S1 is refreshed immediately regardless of the scan time.

When I (input) is used as S1, the actual input status is immediately read into an internal relay starting with M300 allocated to each input available on the SmartAXIS.

When Q (output) is used as S1, the output data in the RAM is immediately written to the actual output available on the SmartAXIS.

Refresh instructions are useful when a real-time response is required in a user program which has a long scan time. The refresh instruction is most effective when using the refresh instruction at a ladder step immediately before using the data.

The IOREF instruction can be used with an interrupt input or timer interrupt to refresh data.

15: REFRESH INSTRUCTIONS


Example: IOREF

The following example demonstrates a program that transfers the input I0 status to output Q0 using the IOREF instruction. Input I2 is designated as an interrupt input. For the interrupt input function, see Chapter 5 "Special Functions" - "Interrupt Input"in the SmartAXIS Pro/Lite User's Manual.

M8125 is the in-operation output special internal relay.

IOREF immediately reads input I0 status to internal relay M300.

M300 turns on or off the output Q0 internal memory.

Another IOREF immediately writes the output Q0 internal memory status to actual output Q0.

Program execution returns to the main program.



HSCRF (High-speed Counter Refresh)


Example: HSCRF

The following example demonstrates a program that updates the current value of high-speed counter HSC1 using the HSCRF instruction. For the timer interrupt, see Chapter 5 "Special Functions" - "Timer Interrupt" in the SmartAXIS Pro/Lite User's Manual.

When input is on, the HSCRF instruction refreshes the high-speed counter current values in special data registers in real time.

The current values of six high-speed counters HSC1 through HSC6 are usually updated in every scan. The HSCRF can be used in any place in the ladder diagram where you want to read the updated high-speed counter current value.

For the high-speed counter function, see Chapter 5 "Special Functions" - "High-Speed Counter" in the SmartAXIS Pro/Lite User's Manual.

D8036 stores 0 to designate jump destination label 0 for timer interrupt.

The interrupt program is separated from the main program by the END instruction.

While the CPU is running, program execution jumps to label 0 repeatedly at intervals selected in the Function Area Settings.


HSCRF updates the HSC1 current value in data registers D8050 and D8051.

When D8050/D8051 exceeds 150000, Q1 is turned on.

IOREF immediately writes the output Q1 internal memory status to actual output Q1.

Each time the interrupt program is completed, program execution returns to the main program at the address where timer interrupt occurred.


16:INTERRUPT CONTROL INSTRUCTIONS

IntroductionThe DI or EI instruction disables or enables interrupt inputs and timer interrupt individually.

DI (Disable Interrupt)

EI (Enable Interrupt)


Valid Devices

Interrupt inputs I0 through I7 and timer interrupt selected in the Function Area Settings are normally enabled when the CPU starts. When the DI instruction is executed, interrupt inputs and timer interrupt designated as source device S1 are disabled even if the interrupt condition is met in the user program area subsequent to the DI instruction. When the EI instruction is executed, disabled interrupt inputs and timer interrupt designated as source device S1 are enabled again in the user program area subsequent to the EI instruction. Different interrupts can be selected for the DI and EI instructions to disable and enable interrupt inputs selectively. For Interrupt Input and Timer Interrupt, see Chapter 5 "Special Functions" - "Interrupt Input" and "Timer Interrupt" in the SmartAXIS Pro/Lite User's Manual.

Make sure that interrupt inputs and timer interrupt designated as source device S1 are selected in the Function Area Settings. Otherwise, when the DI or EI instruction is executed, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

The DI and EI instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

Special Internal Relays M8070-M8075 and M8144: Interrupt Status

Special internal relays M8070 through M8075 and M8144 are provided to indicate whether interrupt inputs and timer interrupt are enabled or disabled.
